Yes — delivery and ongoing support is the final stage of every custom development project, not the end of the relationship.
What to agree before delivery
- Support scope — bug fixes only, or ongoing enhancement?
- Response times for different severities.
- Who maintains it — your team, ours, or both.
- Handover — documentation, architecture notes and knowledge transfer.
- Upgrades — how bespoke work interacts with future platform updates.
That last point deserves attention. On an owned or heavily customized platform, upgrades are included but not automatic in the way they are on a managed platform. Coordinate significant upgrades with support rather than assuming they apply cleanly over modified code — see Release notes and platform updates.
Standard platform support by plan: standard on White Label, dedicated on DSP License, priority dedicated on DSP Acquisition — see What support do you offer?.
A practical recommendation: insist on documentation as a deliverable, not a favour. The most expensive custom systems are the ones nobody remaining can explain.
