An accountant who is right for a stable micro-business may not be right for a company that is hiring, raising funds or opening a second location. Your choice should depend less on geographical proximity or fees than on the firm’s ability to handle the growing complexity of your operations without bringing in a string of external contacts.
Electronic invoicing: the real test of an accounting firm’s readiness
The electronic invoicing reform is the clearest indicator of the level of support an accounting firm actually provides. Early feedback from businesses points to interoperability issues between platforms, rejected invoices and routing errors.
A firm that simply recommends software without supporting you through testing, incident management and any potential switch to a different e-invoicing platform will be of little help when regulatory deadlines become more demanding.
Ask three specific questions before signing an engagement letter:
- How does the firm handle invoices blocked or rejected by the platform, and what is the average resolution time it sees among its current clients?
- Does it support internal processes (approval workflows, expense claims, bank reconciliation), or does it only configure the software?
- If your business invoices both companies and individuals, is the firm familiar with both processes (B2B e-invoicing and B2C e-reporting)?
The answers will tell you whether you are dealing with a data-entry provider or a genuine business partner. A firm equipped to support growth will already have tested these procedures with existing clients, and its teams will have a documented process for each type of incident.
Firms such as those listed on expertell.be make it possible to compare service scopes before committing, helping you avoid discovering gaps after your first year-end close.
Engagement letter and accounting services: what the contract should cover
An engagement letter is a mandatory contract for any accountant registered with the professional body. It sets out the exact scope of services, delivery times and termination terms. Too many business owners sign one without negotiating.
For a growing business, the initial scope should include provisions for change. Moving from a micro-business to a SAS, hiring your first employee or introducing monthly reporting should not trigger a complete renegotiation or a change of firm.
Clauses to check in the engagement letter
The document should specify who is responsible for each task. If the firm outsources data entry or uses automated tools, this must be stated explicitly. Responsibility for VAT errors or late filings must be clearly assigned.
Also check the data portability clause: if you change firms, the timeframe for transferring your accounting records and the file formats (including the FEC) will determine how smoothly the transition goes. A firm that delays returning your data is a major red flag.
Legal and tax advisory expertise for a growing business
Bookkeeping is a commodity. What sets one firm apart from another is its ability to provide value-added advice on the decisions that come with growth: choosing a legal structure when converting your business, optimising the owner’s remuneration, and deciding between paying dividends and reinvesting profits.
A good accountant anticipates regulatory thresholds before you reach them. Becoming subject to statutory audit requirements, crossing employee thresholds and their associated employment obligations, or changing your VAT scheme: if these transitions are poorly planned, they can cost you dearly in penalties and wasted time.
Industry specialisation at the accounting firm
A generalist firm can handle standard accounts competently. A growing business in construction, e-commerce or the liberal professions needs an adviser who understands the specifics of its industry: VAT on the margin scheme, reverse-charge VAT and sector-specific social security contribution schemes.
Ask the firm which industries it serves and how many clients it has with a profile similar to yours. A firm that already works with businesses of your size and in your industry can provide relevant dashboards from the first few months, without making you pay for a learning curve.
Management tools and reporting: beyond traditional accounting
Growth creates a need for real-time visibility into cash flow, margins by business line and budget variances. A firm that delivers annual accounts six months after year-end does not provide this.
Assess the firm’s technology stack: does it use automated monthly reporting tools connected to your business management software? Does it offer online dashboards with configurable metrics? Is bank data synchronised daily or weekly?
These are not just convenience features. For a business owner managing a growth phase, having reliable interim figures by day 10 rather than day 45 can make a real difference to investment and hiring decisions.
Cash flow monitoring and automatic alerts
Tracking unpaid invoices and late payments is critical during a growth phase, when working capital requirements rise faster than revenue. Ask the firm about its alert process: when will it notify you of a cash flow problem, and through which channel?
A firm that waits until the quarterly close to flag a cash flow problem is not a good fit for a business whose operations change every week.
Choosing an accountant to support your growth comes down to practical criteria: expertise in electronic invoicing, an engagement letter that can evolve with your business, proactive legal advice and real-time management tools. Assess the firm against these specific points before comparing fees.
