Two channels into a hard market for Wetaxus

Wetaxus is an Amsterdam accountancy and tax firm. Switching bookkeeper is one of the highest-trust decisions in B2B. closed:in ran two channels at once, an outbound cold email engine and a website visitor identification layer, to surface and warm up demand in roughly six weeks, in a market where buyers rarely switch.

Selling into one of B2B's hardest markets

Wetaxus is an Amsterdam accountancy and tax firm serving Dutch entrepreneurs and SMEs: bookkeeping, tax advice, and pricing tailored by entity type. It competes in one of the most relationship-driven categories in B2B.

Selling accountancy cold is genuinely hard, and it is worth being honest about why. Switching bookkeeper is a high-trust, high-friction decision: it touches a business's finances, it usually waits for the end of a fiscal year, and most owners stay put unless something is actively wrong. A cold email rarely closes that gap on its own. The job was to generate qualified interest in a market where the default answer is "not right now."

Two channels, run together

closed:in did not rely on a single play. Two channels ran in parallel, each feeding the same goal: an outbound engine to create new conversations, and a warm channel to catch demand already circling the brand.

01
Cold email outbound engine
closed:in built an ICP matrix and ran plain-text, multi-step sequences to Dutch businesses, positioning Wetaxus as the switch. Every positive reply was logged into a shared opportunity sheet with contact details and status.
02
Website visitor de-anonymisation
Alongside the outbound, closed:in set up a visitor identification layer on the Wetaxus site. Instead of letting anonymous traffic bounce, it surfaced which companies were on the site, their size and revenue band, and the pages they viewed, including high-intent pricing and contact pages, turning passive traffic into a named, warm follow-up list.
03
Logged opportunities and calling handover
Positive replies and identified visitors were handed to Wetaxus to call and close, with the follow-up tracked call by call, so the team always knew who to chase and when.

Two channels, and an honest read

Across roughly six weeks the program logged around 48 opportunities and, on top of that, a steady stream of named website visitors that turned anonymous traffic into a warm follow-up list. The honest read on a market like this: switching accountant is a slow, high-trust decision, so raw reply volume always overstates how ready buyers are. The value closed:in delivered was the system itself, an outbound engine and a web-intent layer running together, plus the discipline of logging and chasing every signal, rather than any single headline number.

What we would do differently: the two-channel idea was right, the weight was off. In a category this slow to switch, the warm, intent-based channel deserves more of the budget than pure cold volume, and the calling follow-up on positive replies needs to be fast and structured to catch the small share that is genuinely ready to move.
