E-procurement platform custom build cost in London

The verdict in three sentences

For a London logistics group running 50 to 300 supplier tenders a year, a custom e-procurement platform at 4 to 7 M FCFA (about 6,100 to 10,670 EUR) costs less than a single year of an international e-procurement suite (20,000 to 80,000 EUR a year). The features that matter for a client or funder audit are sealed bid submission, a weighted scoring matrix and a timestamped, tamper-proof audit trail. With a realistic target of 3 to 8 % procurement savings, the project often pays back within a year, for a 12 to 16 week timeline.

Why email tendering no longer passes audits

Logistics operators around the Thames Gateway, Heathrow and the London Gateway port work for public bodies, defence and healthcare clients whose procurement rules, and since 2025 the Procurement Act 2023 for public contracts, require proof that bids arrived before the deadline, were opened together and were scored against published criteria. With bids sent by email, that proof is almost impossible to provide.

Sealed submission and the audit trail concentrate the technical difficulty: encryption until opening, server timestamps, write-only logs.

Custom build or e-procurement suite: the numbers

2026 order of magnitude, 1 EUR for about 0.85 GBP. International suites remain justified for a group managing thousands of catalogue items and a full procure-to-pay process. For a need centred on tenders and auditability, custom is more proportionate.

The Kolonell 2026 grid for custom applications: 2.5 to 4 M FCFA (about 3,810 to 6,100 EUR) for a simple app such as a supplier register and price requests, 4 to 7 M FCFA for a medium app (a tendering platform with sealed bids), 7 to 15 M FCFA and up (about 10,670 to 22,870 EUR and up) for a complex app with purchase orders, invoice matching and ERP connection. Maintenance: 35,000, 75,000 or 120,000 FCFA per month (about 50, 110 or 180 EUR).

Where the 3 to 8 % savings come from

Savings do not come from the software itself, but from broader, better documented competition. A supplier knows its bid will be compared on a transparent matrix, and the buyer can invite 5 suppliers instead of 2 without multiplying emails. On spare parts, fuel, handling or security services, a 3 to 8 % gap is a common order of magnitude seen after tendering is digitised.

Mini case study

James, procurement director of a London logistics group, manages 2.7 M EUR of tendered spend a year. With a cautious 3 % savings target, the gain reaches 81,000 EUR a year. The platform costs 9,200 EUR plus 2,200 EUR of annual maintenance: payback comes in under 2 months of tenders. Even if real savings stayed at 1 %, or 27,000 EUR, the project would still pay back in about 5 months.

FAQ

How much does a custom supplier tendering platform cost in London?

Budget 4 to 7 M FCFA, about 6,100 to 10,670 EUR, for a platform with supplier register, sealed bids, scoring matrix and audit trail. With purchase orders and ERP connection, the budget moves to the 7 to 15 M FCFA bracket.

Is an online sealed bid as safe as an envelope?

Yes, if documents are encrypted until opening time and every access is logged. Nobody, administrators included, can read a bid before the opening session.

Will SME suppliers be able to use it?

Yes, submission takes a few minutes from a smartphone, with files up to 20 MB. A short guide and a support line cover 90 % of questions.

Does the platform meet client and funder requirements?

It provides the expected evidence: timestamped receipt, joint opening, scored evaluation and minutes. Each client's rules are configured during a 2 to 3 week scoping phase.

What timeline should we plan?

Plan 12 to 16 weeks, including a real pilot tender with 5 to 10 suppliers before rollout.
