Custom document management system vs SharePoint in London: 2026 cost

The verdict in three sentences

For a company sitting on 15 years of paper archives across 3 sites, a custom document management system costs 25,000 to 60,000 USD in 2026, with a 4-month timeline. Market products such as M-Files or Alfresco cost 15 to 40 USD per user per month, which becomes more expensive than custom beyond 40 users over three years. The most underestimated line remains scanning, at 0.05 to 0.15 USD per page, which must be scoped before choosing the software.

In London, development day rates are roughly 2 to 3 times higher than in Kinshasa, so a comparable custom build lands around 60,000 to 150,000 GBP, and SharePoint, bundled with Microsoft 365, becomes the default benchmark. The method below applies unchanged.

What a document management system must cover

In Kinshasa the constraints are concrete: power cuts, costly and sometimes slow internet, French documents with stamps and handwritten signatures, tax audits requiring invoices from years back. In London, the priorities shift towards UK GDPR, retention policies and Microsoft 365 integration. Either way, the core modules are similar.

A basic version (filing, import, search, rights) starts at 25,000 USD. Workflows and hybrid hosting push it towards 50,000 to 60,000 USD.

Custom, M-Files or Alfresco: the three-year cost

The calculation must include licences, integration, hosting and maintenance. Here is a comparison for 50 users. SharePoint, if already licensed, removes the licence line but usually needs 15,000 to 40,000 USD of configuration to reach the same workflows.

At 50 users, Alfresco and custom are close. At 100 users, licences double and custom becomes clearly cheaper. Custom also gives you approval flows shaped around your internal rules, not the other way round.

Scanning: the real project

Over 15 years, a distribution company often accumulates 800,000 to 1,500,000 pages. Scanning everything is unnecessary. Prior sorting removes duplicates and documents past their retention period, often cutting volume by 40 to 50 %. Price depends on paper condition: 0.05 USD per page for clean stapled bundles, up to 0.15 USD for damaged, bound or mixed-format documents. Plan for 3 to 4 operators and 2 production scanners over 8 to 12 weeks.

Mini case study

Patrick, company secretary of a distribution firm in Kinshasa, estimates his archives at 1,000,000 pages across three sites. After sorting, 550,000 pages remain at 0.08 USD on average, or 44,000 USD. The custom system costs 42,000 USD. His 45 staff each spend about 30 minutes a day searching for documents. If the system cuts that by two thirds, the company recovers 15 hours a day, about 3,300 hours a year. At 12 USD per loaded hour, that is 39,600 USD a year. The total 86,000 USD investment pays back in just over two years, before counting tax penalties avoided during audits.

FAQ

How much does a custom document management system cost?

From 25,000 USD for a basic version to 60,000 USD with workflows, advanced OCR and hybrid hosting in Kinshasa. Scanning archives is priced separately.

How much does archive scanning cost?

Between 0.05 and 0.15 USD per page depending on document condition. For 500,000 pages, budget 25,000 to 75,000 USD, hence the value of sorting first.

Is SharePoint a cheaper alternative?

If you already pay for Microsoft 365, SharePoint removes licence costs, but reaching equivalent workflows and OCR search usually takes 15,000 to 40,000 USD of configuration and add-ons.

Does the system work during internet outages?

With a local server and a UPS, yes. In the cloud, a local cache lets staff read recent documents and sync when the connection returns.

How long until go-live?

Allow 4 months for the software, alongside 8 to 12 weeks of scanning. The first site can be live from month three.
