The Full Cost of Running a SaaS on Five Vendors

Add up five SaaS vendor bills, staff hours, and change costs without counting the same work twice.

The team behind Fieldnote, a hypothetical project tracker, pays five vendors to run the app. As the contracts come up for renewal, the team adds up the invoices and finds that the fees fit its budget. One engineer points out that the team also spent time fixing a missed payment event, work that none of the invoices shows.

Track provider fees, staff time, and the cost of changing tools in separate parts of your budget. Use the same app and workload for each option so you can see whether a different mix of vendors would change the bill, the work, or both.

Start with five jobs and one month

Fieldnote uses separate vendors for API hosting, Postgres, sign-in, payments, and logs. To understand what each service costs, the team picks a typical month and records the dates, customer count, database size, payment volume, and amount of log data it kept. The team includes its test environment because it pays to run that environment too.

The workload tells you whether two prices cover the same job. If one payment bill covers ten purchases and the other covers ten thousand, use the same transaction count before you compare them. Do the same for backup storage if one database quote includes it and the other charges for it separately. The fees and staff hours below are invented for the example.

JobInvented monthly feeWhat the team must check
API hosting$35Capacity, builds, transfer, and test app
Postgres$45Storage, backup use, and restore charges
Sign-in$20Users, messages, and paid plan features
Payments$30Transactions, currency, and extra services
Logs$25Data sent, data kept, and paid seats
Total$155Provider fees

When you make your own sheet, keep the invoice beside each row and record the plan and region if they affect the charge. If several apps share a tool, show how you divided the bill. An equal split gives you a starting point when you lack usage data. Label it as an estimate so a teammate knows how you reached the figure.

Explain the bill before making a forecast

A trial credit may lower one month's bill, while an annual subscription may put a year's worth of fees on a single invoice. Record both the amount you paid and the period it covers so you can compare months. Show credits, taxes, refunds, and one-time charges separately.

For a service billed through AWS, Cost Explorer can help inspect cost and usage. Save the dates and filters you used. Another teammate should be able to open the same view and see where the number came from.

When a line changes, find out whether Fieldnote stored more logs, bought more capacity, or lost a credit. An expired credit, for example, changes what the team should expect to pay even if log volume stays steady.

Once you can explain a typical bill, use it to estimate a busier month. Write down how many customers or transactions you assumed, and label the estimate as a forecast so the team can tell it apart from the charges it has already paid.

Count the work that sits between contracts

Fieldnote's team keeps a work log with the task, the person who did it, the time they spent, and why the work came up. Support tickets, pull requests, and calendar notes can help the team piece together the month. Where the records have gaps, the team marks the hours as estimates.

Suppose the engineers spent three hours on planned checks and two hours fixing that missed payment event. At an assumed staff cost of $60 an hour, the five hours come to $300 in staff time alongside $155 in provider fees. Keep the hours and the rate visible. The founder can use the hours to plan next month's work even when payroll is fixed, while finance can use the dollar estimate for a longer budget.

Log the payment incident once and name the systems it touched in that entry. If the team puts the same two hours under payments, hosting, and logs, the sheet will show six hours for a two-hour fix. Track new product work separately too. Fixing a broken seat update keeps the current app working, while adding a new annual plan belongs in the estimate for building that feature.

Put a price on the proposed change

Suppose Fieldnote is considering a new sign-in vendor with a lower monthly fee. To estimate the work of switching, the team needs to check what it can export, whether account IDs and active sessions will carry over, and how people will sign in afterward. It may need to ask some customers to verify a contact method again.

Before choosing a date, budget for any period with both services running, staff time to test the move, customer messages, and closure of the old account. Work out what the team would do if the switch failed halfway through, since recovery could add work of its own.

Show the cost of the move separately from the usual monthly bill. If you spread that amount across a year for planning, keep the original total and the period visible so the next person can adjust the estimate.

You should also record why each specialist earns its place. Fieldnote may need a payment feature that its hosting platform does not offer. Its fee remains part of the future stack even if other jobs move.

Use the same sheet to evaluate Forte

Forte includes application logs, request records, managed ingress, and data transfer without separate add-on fees. Backend compute, builds, and databases still have their own meters. Use the pricing docs to list those meters for Fieldnote's workload, then keep any remaining outside providers on the sheet.

Check the operating work with a small trial. Deploy a test API, release a change, and cause a safe request failure. Ask a teammate to find the failed request and its app output. The app must emit Forte's request ID for precise matching between a request and its log lines. The debugging walkthrough explains that path.

Record the steps the teammate took to find the failure. A shared view may save them from searching a second tool, while payment rules and account recovery still need work in the app. Use this trial to estimate the effort for the task you tested and decide what else to check before projecting a monthly saving.

For a wider budget, use the total cost of ownership guide. If you want a Forte estimate, use the form below with the five jobs, rough usage, and tools you need to keep. Leave out private invoices, customer data, and credentials.
