The verdict in three sentences
An SME with a 95-day DSO ties up roughly USD 400,000 (4 million MAD for a Casablanca firm) in customer receivables. An automated dunning workflow across email, SMS and WhatsApp, with an embedded payment link, costs USD 10,000 to 20,000 in Dubai (40,000 to 90,000 MAD in Casablanca) and brings DSO down to around 65 days within two quarters. The cash released, around USD 120,000 to 130,000, far exceeds the project cost.
Why manual chasing fails
In most SMEs, collections depend on an accountant who calls customers when time allows, often 45 or 60 days after the due date. Small invoices are never chased, large accounts are chased too late, and nobody reminds the customer before the due date. The result: a growing receivables balance and overdraft costs.
| Indicator (2026 order of magnitude) | Manual chasing | Automated dunning |
|---|---|---|
| Average DSO | 95 days | 65 days |
| Receivables on USD 1.5M annual revenue | about USD 400,000 | about USD 270,000 |
| Invoices reminded before due date | under 5% | 100% (D-5) |
| Weekly collections time | 10 to 12 h | 2 to 3 h (disputes only) |
| Share paid within 3 days of the D-5 reminder | negligible | 25 to 35% |
| Overdraft cost on excess receivables (6 to 7% rate) | USD 8,000 to 9,000/year | cut by a third |
| Disputes detected early (contested invoice) | at D+60 | at D+3 |
The pre-due-date reminder is the highest-return lever: many delays are not bad faith but an invoice lost in the customer's approval chain.
The standard workflow and its budget
The workflow reads data from your ERP or invoicing software (Sage, Odoo, Zoho Books, QuickBooks) and adapts tone to the delay and customer profile. In the UAE, WhatsApp is often the channel that gets a reply first.
| Step | Channel | Content |
|---|---|---|
| D-5 | Polite reminder, PDF invoice, payment link | |
| D+3 | Email and SMS | Notice of delay, request to confirm payment run |
| D+15 | WhatsApp Business and email | Firm reminder, payment plan offer, direct accountant contact |
| D+30 | Scheduled call | Task assigned to the collections lead |
| D+45 | Formal notice | Generated template, approved by the CFO |
| D+60 | Order block | Alert to sales rep and order desk |
| Item | Dubai 2026 (USD, excl. VAT) | Casablanca 2026 (MAD, excl. VAT) |
| Scoping, customer segmentation and message templates | 1,500 to 3,000 | 6,000 to 12,000 |
| ERP or invoicing software connection | 2,500 to 5,500 | 10,000 to 25,000 |
| Workflow engine and DSO dashboard | 3,000 to 5,500 | 12,000 to 25,000 |
| WhatsApp Business API and SMS integration | 1,500 to 3,000 | 6,000 to 14,000 |
| Payment link (card gateway, bank transfer) | 1,500 to 3,000 | 6,000 to 14,000 |
| Total | 10,000 to 20,000 | 40,000 to 90,000 |
| Recurring (SMS, WhatsApp, hosting) | USD 150 to 400/month | 800 to 2,500 MAD/month |
Deployment takes 6 weeks, including 2 weeks of testing on a sample of 30 customers. Remember that UAE VAT at 5% applies to the project.
Mini case study
Nadia, CFO of an electrical equipment distributor, runs USD 1.5 million in revenue with a 95-day DSO. She invests USD 15,000 plus USD 250 a month. Moving to 65 days cuts receivables by about USD 123,000. At a 6.5% overdraft rate, interest savings reach USD 8,000 a year, plus 8 hours of chasing saved each week, worth about USD 9,000 a year at a USD 22 loaded hourly cost. Payback in about 10 to 11 months, with USD 120,000 of cash released from the second quarter. The same project in Casablanca at 65,000 MAD pays back in under 10 months on interest alone.

FAQ
Won't WhatsApp reminders upset our customers?
Tone is set per segment: a key account gets a personalised email from the accountant, a small business a short WhatsApp message. SMEs that test it see under 2% complaints.
What are the legal payment terms?
In Morocco, law 69-21 sets 60 days absent agreement and 120 days maximum. In the UAE, terms are contractual, so clear terms on the invoice and documented reminders strengthen any later claim.
Can we embed a card payment link?
Yes, via a local payment gateway, for USD 1,500 to 3,000 of integration. 20 to 30% of small invoices are then paid directly from the message.
Do we need to change our accounting software?
No. The workflow reads invoices and payments from your existing tool, via API or daily export.
How quickly does DSO improve?
The D-5 reminder works from the first month. The full drop from 95 to 65 days usually takes 4 to 6 months.
