The business in one offer
Who it serves
SaaS companies with two to ten developers and no dedicated tester, who ship every one or two weeks and keep getting bug reports from customers after releases. A founder or engineering lead pays because developers testing their own code miss problems and it pulls them away from building.
What to sell first
A release testing retainer: a written regression test plan for the core user journeys, one manual pass across two browsers and one mobile device before each release, and a bug report delivered in the team's issue tracker within one business day. Excluded: load testing, security testing, and automation beyond a few smoke tests.
A fixed test plan per release is easy to price and schedule, and the client sees concrete output in their own tracker within days. The plan grows into an automation backlog, which creates natural follow-on work.
What could it cost to start?
This is an original example budget for the limited pilot described above. It is not a researched market average or a complete quote for every location.
| Item to price | Example allowance |
|---|---|
| Cross-browser and device testing service, three months | $300.00 |
| Used Android phone and tablet for real-device checks | $300.00 |
| Screen recording and test case management tools | $90.00 |
| Website and sample test plan | $120.00 |
| Professional liability insurance quote allowance | $450.00 |
| Contract and NDA template review | $300.00 |
| Example total | $1,560.00 |
What this assumes—and excludes
Assumes you already have testing experience, a reliable computer and an iPhone, and can read basic code. Excludes owner pay, client tool licenses, paid ads and office costs. Prices for device clouds change, so compare current plans before buying, and get insurance quotes for your state.
Collect actual supplier, insurance and local-authority information. Add a reserve for delays and unexpected costs; the example total is not a funding recommendation.
How the unit economics work
At an assumed $1,600.00 per monthly retainer and $60.00 in direct costs, contribution is $1,540.00 before monthly fixed costs, owner pay and taxes. With 24 all-in working hours per unit, that is $64.17 per delivery hour before those deductions. These inputs illustrate the arithmetic; they do not establish a market price or expected earnings.
The example also allows $140.00 in monthly fixed costs. Include unpaid acquisition and administrative time when deciding whether the offer is worthwhile.
Try your own numbers
These are editable planning assumptions, not prices we have verified. Calculations stay in your browser.
Operating result = (price − direct cost) × units − monthly fixed costs. Before owner pay, taxes, financing and startup recovery. At these inputs, delivery requires 240 hours per month, plus any work not included in your per-unit estimate. Sales volume is a scenario, not a forecast.
How to find the first customers
Test a small offer before scaling traffic. Record the source of each enquiry, whether it fits the offer, and whether the buyer pays.
- Offer a free one-hour exploratory test of a public sign-up flow for five small SaaS products you use, and send the bug report privately to the founder with no strings attached.
- Ask developers in your network which teams ship often without a tester, and offer a two-release trial at a reduced rate so the team sees the report format.
- Publish a sample regression plan for a fictional project management app, showing how you prioritize journeys, so leads can judge your approach.
- Ask each retainer client whether you may say that you test their releases, and keep a short record of bugs caught before release for your own planning.
What to validate before spending more
- Time two full regression passes for a pilot client, including writing reports, and compare with the hours your price assumes before signing other retainers.
- Confirm with each client what test data you may use and whether you will touch production. Testing in production without approval can create real orders or emails.
- Check the device cloud's terms on where screenshots and recordings are stored, since they may capture client data.
- Track how often client releases slip in the first month. If late code regularly squeezes your testing window, add a cut-off time to the contract.
The operational catch
When a bug reaches customers anyway, clients may decide testing failed, even if the feature was outside the plan. Agree in writing which journeys and devices the plan covers, log what was tested in each release, and review the plan monthly so scope matches what the team ships.
A practical way to fund the first step
Bill the first month in advance, which covers device tools and insurance. Start with monthly device cloud plans and one or two used phones instead of a device lab, and add hardware only when a client's users depend on it.
Separate cash already available from money still to earn. Count only proceeds after direct expenses, and do not spend customer funds needed to fulfill their existing orders.
Questions before you start
Do I need a certification to sell testing?
No license is required, and certifications are optional. Clients care more about clear bug reports and an organized test plan. A sample report and plan often do more than a certificate.
When should I start automating tests?
Once a manual test has passed several releases unchanged and covers a critical path, such as sign-up or checkout. Automating changing features too early leads to brittle tests and wasted hours.
Can I test apps that handle health or payment data?
Possibly, but those clients may require extra security steps and agreements. Ask what data you will see, use test accounts, and get advice before signing contracts that involve regulated data.
