Accounting Firm Client Document Portal: Cost and Adoption in 2026

The verdict in three sentences

For a firm with 35 staff and 600 clients, a client portal that collects documents continuously and flags tax deadlines frees the equivalent of one to two full-time staff. Off-the-shelf portals cost around 15,000 to 40,000 MAD a year and are enough if your processes are standard; a custom build makes sense once you need to plug into your production software, engagement letter templates and portfolio-based organisation. A custom project takes 3 to 4 months, and Kolonell's budget is set in the quote after scoping.

The real cost of chasing documents

In a firm in Casablanca, or any busy practice, the run-up to monthly or quarterly VAT deadlines turns into a scramble: WhatsApp reminders, crooked receipt photos, bank statements sent in pieces, bags of paperwork dropped at reception the day before the deadline. Each staff member spends on average 30 to 45 minutes per client per month requesting, sorting and renaming documents.

Off-the-shelf portal or custom build

The choice depends less on price than on integration. A standard portal goes live in weeks but imposes its own workflow. A custom portal fits your portfolios, your roles (partner, manager, assistant) and your accounting production software.

Core features of a custom portal: mobile app or responsive web to photograph invoices, OCR extracting date, net amount, VAT and supplier, a per-client tax calendar (VAT, quarterly corporate tax instalments, annual return), a dashboard of missing documents per staff member, and e-signature of filings and engagement letters. Electronic filing itself stays on the tax authority's portal (SIMPL in Morocco); the portal prepares and tracks, it does not replace it.

Getting clients to adopt it

A portal is only worth something if clients use it. Firms that succeed start with 50 volunteer clients, demo the app in meetings, then make digital submission mandatory in the next engagement letter. Realistic target: 60% active clients at 6 months, 80% at 12 months.

Mini case study

Mr. Benjelloun, partner at a Casablanca firm, has 600 clients and estimates 40 minutes per client per month spent obtaining and filing documents, i.e. 400 hours a month. With 70% of clients active on the portal and 30 minutes saved per active client, the firm saves 420 clients × 30 min, i.e. 210 hours a month.

At an internal cost of 150 MAD an hour, savings reach 31,500 MAD a month, or 378,000 MAD a year. An off-the-shelf portal at 40,000 MAD a year would pay back in under two months, provided it integrates with his software. A custom build is therefore compared over 3 years: build and maintenance cost against the extra gain from full integration, which scoping quantifies precisely.

FAQ

Will older or less equipped clients use the portal?

Some will not, and that is fine: paper drop-off stays available for them. Reaching 60% active clients at 6 months already frees over 150 hours a month across 600 clients.

Can the portal file returns with the tax authority?

No, electronic filing stays with the firm on the official tax portal. The portal prepares documents, tracks the deadline and archives the filing receipt.

Where is client data hosted?

Hosting is chosen during scoping, in line with local data protection law. Documents are encrypted and every access is logged.

How long does a custom portal take?

Allow 3 to 4 months: 3 weeks of scoping, 8 to 10 weeks of development, then a pilot with 50 clients. The budget is set in the quote after scoping.

Is OCR reliable on local invoices?

On printed invoices, extraction of date, amount and VAT exceeds 90% accuracy. Crumpled or handwritten receipts are still checked by staff.
