International expertise.
Locally delivered.
We are a boutique, partner-led accounting and audit firm delivering audit & assurance, advisory, fractional CFO and sustainability across Canada, the UK, the UAE and Spain.
Why Black Maple
Audit and advisory don’t have to work the way you’re used to.
You know how it usually goes. You meet the partner once, at the pitch. After that it is a different junior every year, each one learning your business from scratch. A straightforward question takes three emails and a fortnight. Then the fee arrives, and it is bigger than the quote.
We built Black Maple to work the other way round. A partner runs your engagement from the first call through to the final report, whether that report is an audit opinion or a month-end close. The person making the judgements is the person you ring. Nothing goes offshore, and the fee we quote is the fee you pay.
Most of our clients have outgrown a sole practitioner but do not want to pay Big Four rates for a name on the front page. We work where ISA, CAS and IFRS meet, so whether it is an audit, a transaction or your finance function, you deal with senior people who give you a straight answer and a fixed fee.
We are taking on any year end, busy season included. Most engagements start within three weeks of appointment.
Boutique attention
Partner-led engagements. You work directly with the people making the judgements, start to finish.
Cross-border capability
One firm across five countries, working where ISA, CAS and IFRS meet.
Modern delivery
Independent, objective and technology-enabled auditing built for how businesses actually operate.
Fees
Boutique does not mean expensive
It means senior people and a light cost base. We do not run prestige city-centre floorspace, a graduate intake learning on your file, a national marketing budget or an international network levy, so none of that sits inside your fee.
Our charge-out rates are around half those of a comparable mid-tier firm. Allowing for a more senior team doing the work, clients typically see a total fee 15% to 30% lower, agreed as a fixed number before we start.
