How work is contracted
Work is contracted in four ways, depending on the nature of the engagement. The amount is always agreed in writing before anything starts, and work with a defined scope is quoted at a fixed price.
Contracting options
Fixed-price project
For work with a defined scope, such as a regulatory adaptation or an audit. The price is agreed before starting and does not change unless the scope changes in writing.
Monthly fee
A number of hours per month with response times set in the service level agreement. It reserves capacity, and is the usual arrangement for ongoing maintenance.
Prepaid hours
A number of hours bought in advance and drawn down as needed. Hours do not expire and any unused balance is refundable.
Hourly, on demand
For one-off work with no commitment to continue. Time spent is invoiced, with an estimate up front where the work allows one.
To give you a figure we need to know what the application does, what it is built on and what you need to resolve. We then prepare a written quotation.
Support
Standard support keeps everything moving. Priority is for systems where minutes matter: paged response, phone and after-hours cover.
| Tier | Channels | Response time | Coverage |
|---|---|---|---|
| Standard | Email and messaging | 48 business hours | Monday to Friday, 9:00 to 18:00 CET |
| Priority | Phone, email, Slack | P1: 1hr, P2: 4hr, P3: 8hr | 24/7 |
Always invoiced separately, regardless of the size of the monthly fee.
