This SaaS business plan is a complete sample for a bootstrapped software start-up in Munich that sells a job management and e-invoicing app to small trade businesses. It’s for founders building subscription software who need a plan for a bank, a public loan programme or early investors. Change the product, pricing and customer numbers; keep the SaaS metrics and the structure.
All figures are in euros, excluding VAT. The company is fictional; the tax rates, rules and market figures are real for Germany. Start from our blank business plan template if you like, or browse other sample business plans.

SaaS business plan: executive summary
Auftragsmeise is a mobile and web app that lets small trade businesses (electricians, plumbers, painters, carpenters) run jobs from quote to invoice. Staff record time, photos and materials on site; the office turns that into an invoice in German e-invoice formats in one click.
The timing is good. Germany’s e-invoicing rules for business-to-business sales are phasing in between 2025 and 2028, and many small trade firms still invoice from Word or paper. They need a simple tool, fast.
We plan 150 paying customers by the end of Year 1, 480 by Year 2 and 900 by Year 3. Revenue grows from €69,310 to €589,370. We lose €130,826 in Year 1 and €57,179 in Year 2, then make a net profit of €45,669 in Year 3.
The founders invest €220,000; we’re asking our house bank for a €120,000 KfW start-up loan. We’re not raising venture capital: the plan is built to reach profit on this money alone.
Company overview
Auftragsmeise was founded by Lukas Huber, a master electrician who ran a six-person firm for eight years before moving into product management, and Aylin Demir, a software engineer with ten years at Munich software companies.
Mission
Give small trade businesses their evenings back. Paperwork should take minutes, not the hours after a day on site.
Legal form
The company is a GmbH registered in the commercial register in Munich. Share capital is €25,000, paid in from the founders’ equity; each founder holds 50%. A GmbH limits personal liability, which matters when you hold customers’ business data, and it’s the form German banks and public lenders expect.
Milestones
- Year 1: launch, 150 paying customers, e-invoice formats certified against current standards.
- Year 2: 480 customers, first developer and a working-student support role, accountant integrations.
- Year 3: 900 customers, a sales hire, an office in Munich, positive EBITDA.
Products and services
Three plans, priced per company not per user, because trades owners hate paying for each apprentice’s login.
| Plan | Price per month (ex VAT) | Who it’s for |
|---|---|---|
| Solo | €29 | One-person businesses: job sheets, quotes, e-invoices |
| Team | €69 | Up to 5 users: scheduling, mobile time tracking, photo reports |
| Betrieb | €139 | Up to 15 users: everything plus stock, multi-site jobs and accountant export |
| Onboarding package | €290 one-off | Data import, templates set up, one-hour training call |
| Annual billing | 2 months free | Pay yearly, get 12 months for the price of 10 |
The blended average works out at about €58 per account per month in Year 1, rising to €64 by Year 3 as customers move up from Solo. We assume 35% of new accounts buy the onboarding package.
Product roadmap
Year 1 is about doing the basics brilliantly: quotes, job sheets, invoices. Year 2 adds accountant integrations and stock tracking for the Betrieb plan. Year 3 adds supplier price lists from wholesalers, so materials flow straight from the order into the invoice. Every roadmap item has to pass one test: does it save a trades owner time this week?
Core features
- Quotes and invoices with German VAT handling and e-invoice output.
- Mobile job sheets with time, materials, photos and customer signature, working offline in basements.
- Drag-and-drop scheduling for teams of up to 15.
- Export to the firm’s tax adviser in standard German accounting formats.
Market analysis
The national market: German trades
The market is big and fragmented. The German Confederation of Skilled Crafts (ZDH) counted 1,038,126 craft businesses at the end of 2025, with estimated turnover of €783 billion. Most are small, owner-run firms with no IT department.
E-invoicing turns a nice-to-have into a must-have. Since 1 January 2025 the general e-invoice obligation applies between domestic businesses; from 1 January 2027, firms with prior-year turnover above €800,000 must send e-invoices in B2B sales, and from 1 January 2028 all businesses must, as the IHK Frankfurt sets out.
Munich and Bavaria
We start in Munich and Upper Bavaria, where Lukas knows the trade guilds and wholesalers personally. Bavaria has a large craft sector and high labour costs, so saving office hours has a clear euro value for owners here. After Year 1, customers come from across Germany through online channels.
Target customers
- Owner-operators (1 to 3 people) who invoice in the evenings: Solo and Team plans.
- Small firms with 4 to 15 staff and one office person: Team and Betrieb plans.
- Our first focus trades: electrical, plumbing and heating, painting, carpentry.
Competition
Craft-trade software isn’t new. What’s missing is a product a busy owner can set up without a consultant and afford on a monthly plan.
| Competitor type | Strength | Our angle |
|---|---|---|
| Established craft-trade software suites | Deep features, long track record | Set up in an afternoon, no consultant needed, fair monthly price |
| General accounting and invoicing apps | Cheap, familiar to accountants | Built around jobs on site, not around bookkeeping |
| Field-service platforms from abroad | Polished, well funded | German-first: trades terminology, e-invoice formats, local support |
| Paper, Excel and WhatsApp | Free, familiar | Saves 4 to 6 office hours a week and gets invoices out the same day |
Marketing and sales
Customer acquisition cost is the number that kills most SaaS businesses, so this SaaS business plan leans on cheap, trust-based channels.
- Tax advisers: partner programme with Munich tax advisers who serve trades clients; they get a free account and a referral commission.
- Trade guilds and wholesalers: talks at guild evenings and stands at wholesaler open days.
- Search: content and ads around e-invoicing questions trades owners are typing right now.
- Free trial: 30 days, no card needed, with a call from a founder on day two.
- YouTube: short how-to videos filmed on real job sites.
Marketing spend is €30,000 in Year 1 and €80,000 in Year 3. With about 168 new accounts in Year 1, that’s roughly €179 per new customer, recovered in about 4 months of gross profit.
Operations
Premises and people
We start with two flexible desks in a Munich coworking space for €400 a month, moving to a small office in Year 3. Development, support and sales run in-house; design and penetration testing are contracted out.
Technology and suppliers
- Hosting in German data centres with a major cloud provider, budgeted at about €4 per account per month.
- An e-invoicing validation service at about €1.50 per account per month.
- Payment processing at around 2% of revenue.
Registrations and rules
- Notarised founding of the GmbH, entry in the commercial register, trade registration with the City of Munich and tax registration with the tax office. IHK membership follows automatically.
- GDPR: a data processing agreement with every customer, a data protection officer service, and hosting inside the EU.
- Invoicing software must support German bookkeeping rules on record keeping and tamper-proof archiving, and the current e-invoice formats.
- Corporate tax: 15% corporation tax plus the 5.5% solidarity surcharge on it, and trade tax at Munich’s multiplier of 490%, per the City of Munich. Together that’s about 33.0% of profit.
Management and team
Lukas Huber, CEO: master electrician and former business owner. Product, sales, partnerships and finance.
Aylin Demir, CTO: backend and mobile engineering, security and infrastructure.
Hiring plan: a full-stack developer and a working student for support in Year 2; a sales manager and a second support person in Year 3. Product and development staff costs (including employer social contributions) are €100,000 in Year 1, €165,000 in Year 2 and €230,000 in Year 3. Both founders take below-market salaries until Year 3.
SaaS start-up costs
A SaaS business plan needs most of its money for runway, not equipment. Ours is no different.
| Item | Cost |
|---|---|
| Product build before launch (capitalised) | €45,000 |
| Laptops, test devices and screens | €15,000 |
| GmbH formation, notary and trademark | €6,000 |
| Data protection and contract templates | €4,000 |
| Launch marketing | €15,000 |
| Working capital (funds early losses) | €225,000 |
| Contingency | €30,000 |
| Total start-up capital | €340,000 |
Total start-up capital is €340,000: €220,000 from the founders and a €120,000 bank loan. The working capital and contingency (€255,000) are the runway that carries us through Years 1 and 2.
Financial plan
SaaS metrics
| Metric | Year 1 | Year 2 | Year 3 |
|---|---|---|---|
| Paying customers at year end | 150 | 480 | 900 |
| Average revenue per account (monthly) | €58 | €61 | €64 |
| Annual recurring revenue at year end | €104,400 | €351,360 | €691,200 |
| Monthly churn assumed | 2.0% | 2.0% | 2.0% |
| Gross margin | 74% | 79% | 81% |
Unit economics
A SaaS business plan stands or falls on whether a customer is worth more than they cost to win. Ours: about €179 to acquire, about €43 of gross profit a month, and an expected life of around 50 months at 2% monthly churn. That’s a lifetime gross profit of roughly €2,100 per customer, more than ten times the acquisition cost.
Assumptions
- Paying customers at year end: 150, 480, 900, 1,300, 1,650 for Years 1 to 5, with 2% monthly churn already netted off.
- Revenue = average customers x average monthly revenue per account x 12, plus onboarding fees.
- Cost of sales: hosting, e-invoice validation, payment fees, a €12,000 base for monitoring and tools, and support staff from Year 2. Gross margin 74% rising to 81%.
- Operating costs: product and development staff, sales from Year 3, marketing, office and €29,000 a year for legal, accounting, data protection, software and insurance.
- Product build and equipment (€60,000) depreciated over five years; replacement hardware of €8,000 to €10,000 a year from Year 3.
- Bank loan €120,000 at 5% over five years. Tax at about 33.0%, with Year 1 and 2 losses carried forward, so no tax is due until Year 4.
Three-year profit and loss for this SaaS business plan
| Line | Year 1 | Year 2 | Year 3 |
|---|---|---|---|
| Revenue | €69,310 | €271,760 | €589,370 |
| Cost of sales | €18,336 | €58,225 | €114,327 |
| Gross profit | €50,974 | €213,535 | €475,043 |
| Operating expenses | €163,800 | €253,800 | €412,000 |
| EBITDA | -€112,826 | -€40,265 | €63,043 |
| Depreciation | €12,000 | €12,000 | €13,600 |
| Interest | €6,000 | €4,914 | €3,774 |
| Tax | €0 | €0 | €0 |
| Net profit | -€130,826 | -€57,179 | €45,669 |
The pattern is classic subscription software: losses while the customer base builds, then profit climbs quickly because each extra customer costs very little to serve. EBITDA turns from -€40,265 in Year 2 to €63,043 in Year 3.
Five-year summary
| Line | Year 1 | Year 2 | Year 3 | Year 4 | Year 5 |
|---|---|---|---|---|---|
| Revenue | €69,310 | €271,760 | €589,370 | €938,480 | €1,274,940 |
| Net profit | -€130,826 | -€57,179 | €45,669 | €177,187 | €266,472 |
| Closing cash | €112,558 | €39,030 | €57,654 | €207,336 | €445,393 |
The low point for cash is the end of Year 2 at €39,030. That’s tight, so the risk table below sets clear triggers for cutting spend. Our guide to financial projections for a business plan explains how to build this kind of runway view.
Funding request and use of funds
We’re asking for a €120,000 loan through our house bank under KfW’s ERP start-up loan programme, which lets young firms borrow up to €125,000 with KfW taking 80% of the bank’s default risk, according to KfW. We assume 5% interest over five years, about €27,717 a year; the actual terms will come from the bank.
- €60,000 product build and equipment.
- €25,000 formation, legal, data protection and launch marketing.
- €255,000 runway and contingency.
Risks and mitigation
A SaaS business plan should be honest about runway. Ours has about two years of it, so we watch these risks every month.
| Risk | Impact | How we reduce it |
|---|---|---|
| Slower customer growth | Cash runs low in Year 2 | Monthly review; cut marketing and delay the Year 2 hire if adds fall 25% below plan |
| Churn higher than 2% a month | Revenue stalls | Onboarding package, in-app checklists, call every account in its first 30 days |
| Bigger rivals copy e-invoicing features | Weaker sales message | Compete on ease of use, price and trade-specific workflows |
| Data breach or outage | Lost trust, legal exposure | Hosting in German data centres, daily backups, external penetration test yearly |
| Founders’ key-person risk | Development stops | Documented code, second developer in Year 2, key-person insurance |
Stress-testing this SaaS business plan
For subscription software the test that matters is runway: how long the cash lasts if customers sign up more slowly. Year 2 is the pinch point for Auftragsmeise, so that’s where this test looks.
| Year 2 scenario | Revenue | EBITDA | Cash at end of Year 2 |
|---|---|---|---|
| Base case | €271,760 | -€40,265 | €39,030 |
| Revenue 10% lower | €244,584 | about -€61,600 | about €17,700 |
| Revenue 20% lower | €217,408 | about -€83,000 | about -€3,700 |
These figures assume cost of sales falls in line with revenue. Support staff and the monitoring base don’t, so read them as the best version of a bad year. A 20% miss in Year 2 runs the cash out before Year 3.
That’s why the risk table carries a hard trigger: if new customers fall 25% below plan, marketing is cut and the Year 2 hire is delayed. Banks and investors will build this runway test themselves if you don’t, so put it in your business plan.
Where the SaaS start-up costs could flex
- Launch marketing (€15,000): a paid pilot with a small group of trade firms gives you case studies and costs less than ads.
- Laptops, test devices and screens (€15,000): the test devices are needed; the rest can be leased.
- Product build before launch (€45,000): a narrower first release, built around the jobs trade firms do every day, keeps this line in check.
Never trade runway for nicer kit. The €255,000 of working capital and contingency is what gets the company to profit in Year 3.
How to adapt this subscription business plan for the UK, Europe, US or elsewhere
- UK: a limited company and UK corporation tax; Making Tax Digital rules drive demand for similar software. See our UK business plan guide.
- Germany and the rest of Europe: check local e-invoicing timelines, which differ by country, and trade tax rates if you’re in Germany. Our Germany business plan page and Munich business plan page cover local detail.
- US: SaaS sales tax rules vary by state, salaries are higher, and many products price per user. Read our US business plan guide.
- Any SaaS: keep the metrics table (customers, revenue per account, churn, gross margin). Investors and lenders look there first.
Tip: model churn honestly. A SaaS business plan that assumes 0.5% monthly churn for small businesses will look brilliant and fall apart in the first year.

SaaS Business Plan FAQs
How much money do you need to start a SaaS business?
The SaaS start-up costs in this bootstrapped Munich sample come to €340,000, most of it runway to cover two loss-making years while customers build up. Funded start-ups that hire faster need much more.
What metrics should a SaaS business plan include?
Paying customers, average revenue per account, churn, annual recurring revenue, gross margin and customer acquisition cost. Show them yearly next to the profit and loss.
When does a SaaS company become profitable?
Often not before Year 3. This SaaS business plan turns EBITDA positive in Year 3 because costs stay lean and churn is assumed at 2% a month.
Can a SaaS start-up get a bank loan?
Yes, especially with public support. In Germany, KfW’s start-up loan programme works through your house bank. Lenders will want to see founder equity and a realistic runway.
What gross margin is normal for SaaS?
Above 70% is typical once you include hosting, payment fees and support. This plan runs at 74% in Year 1 and 81% by Year 3.
