Discovery for a broker CRM spends a disproportionate amount of time on the meter- point data model: confirming how MPAN core, top line and MPRN values are currently captured across existing spreadsheets or CRMs, and where they conflict between sources. Getting this model right before build starts is what allows the Contract-End-Date-driven pipeline and portfolio views to work correctly on day one, rather than needing a data-model rework six months in.
Supplier price feed integration cost varies more than most cost drivers because feed quality and format consistency vary by supplier — some publish clean, versioned feeds; others require a scraping or manual-upload fallback that has to be built and maintained. We scope each panel relationship individually during discovery rather than quoting a flat per-integration figure across the board.
Because renewal activity clusters around contract end dates, the system needs to perform reliably under load during renewal-heavy periods rather than on an average day. This affects the ongoing support band more than the build cost, but it is worth budgeting for a support arrangement with faster response times during known renewal peaks rather than a flat SLA year-round.
