From engagement letter to fee note in an Omani firm

The engagement letter is where billing starts, even though finance rarely sees it. It sets the scope, the fee basis, the billing frequency and what happens with expenses. In many Omani firms, though, those terms are filed as a document and then re-keyed into the accounting system from memory or not at all. Fee notes end up inconsistent with what the client signed, and disputes follow.

Each profession adds its own pattern. Law firms open matters for litigation, transactions or advisory work, often with hourly rates, caps or stage fees. Audit and accounting practices run annual engagements with installment billing and a heavy season after year end. Engineering and design consultancies bill by project stage and frequently work for ministries or state-owned developers, where payment follows formal approval of each submission.

I design one engagement record that carries the terms of the letter: client, entity, fee basis, rates or fixed amounts, billing schedule, expense policy and responsible partner. Time, disbursements and fee notes all hang from it. The general model is set out on my professional services ERP page, and engineering firms needing deeper project control should also see the engineering ERP page for Oman.

VAT on fees, disbursements and correspondent firms

Professional fees charged by Omani firms are generally subject to VAT, though fees for clients outside Oman may be handled under other rules that your advisor will explain. The finer questions are about what sits around the fee. Is a court fee paid on the client's behalf a disbursement outside the scope of VAT, or a recharge that forms part of your taxable supply? How is a travel cost billed on to a client treated? Your tax advisor answers these. I make sure the system can apply each answer through distinct expense types and tax codes.

Many Omani firms work closely with correspondent or network firms abroad: foreign counsel on a cross-border transaction, an overseas audit component, a specialist design studio. When those firms invoice the Omani practice, the services are imported, and the reverse charge mechanism generally means the Omani firm accounts for the VAT. I design supplier records with country and service type, link each foreign invoice to the matter it supports, and add a review step so the treatment is checked before posting.

An e-invoicing framework is also being prepared by the tax authority. Its details may change, so the sensible step today is consistent client tax data and a single source for fee notes.

Measuring WIP and lock-up when public clients pay slowly

For many Omani firms, a meaningful part of fee income comes from government bodies, state-owned companies and large family groups. These clients often have structured approval procedures: a fee note may need a purchase order reference, a stage approval letter or sign-off by a department head before it enters the payment queue. That stretches debtor days, and if time is also recorded late inside the firm, lock-up grows from both directions.

I separate the two halves so partners can act on each. On the WIP side, the design covers weekly time entry, monthly partner review, write-down approvals with a reason, and alerts when an engagement's unbilled value passes a threshold the firm sets. On the receivables side, each open fee note carries a status that explains what it is waiting for, so follow-up goes to the right person on the client side.

The Omani rial's three decimal places matter here too. Hourly rates, fixed stage fees, VAT and rounding should agree across fee notes, statements and bank receipts, so I test them with real figures in each shortlisted platform. Reporting then shows lock-up by partner, practice area and client type. Much of this work happens within my ERP gap analysis before any software is chosen.

Retainers, firm data and selecting a platform

Retainers and advances are common across Omani professional work, from monthly legal advisory arrangements to accounting firms that handle bookkeeping or payroll for a fixed fee. I design these as client balances with clear rules: what is covered, how hours are counted, what happens on overrun and when the arrangement renews. Clients then receive statements they can reconcile, and partners see whether each retainer is actually profitable.

Firm data needs attention as well. Professional firms in Oman may be asked about the employment of Omani nationals and the qualifications of people on an engagement, so HR and staffing records should hold nationality, grade, role and professional credentials in one consistent place.

When selecting a platform, I test practice management tools connected to accounting software against ERP options on engagement intake, WIP review, retainer handling, VAT and reverse charge, rial precision and bilingual documents. Advisory firms that staff mandates from one shared pool will find a closer match in my Omani consulting firm ERP notes. I work remotely with Omani firms throughout.
