Almost nobody in the directory lists Morocco as their base yet. The experts listed here are spread across other countries, and each takes on African clients, so you'll be hiring across a border. Set the job up for that from the first call.
Which language will you work in? Decide whether briefs, calls and handover notes run in French, Arabic or English, and hire someone fluent in it. Misread instructions cost more than any difference in rates.
When are they online? Agree a daily window of shared working hours and a named contact for urgent fixes. A checkout that fails on a Friday evening can't wait for Monday.
What currency is the contract in? Your shop takes dirham; your expert likely invoices in euros or dollars. Fix the contract currency, agree who bears exchange-rate movement, and pay by milestone rather than upfront.
Who owns what? Put the store, the web address, the provider account and each paid app under your company's name. The expert works through a staff account you can switch off.
Who else have they built for? Request one working store with Moroccan customers, then go through its checkout and its dirham pricing yourself. One relevant reference outweighs a dozen unrelated ones.
An expert without Moroccan references can still be the right choice for theme design. For payments and tax, insist on one.
