The Cost Of Slow Payments

One in four B2B buyers has fired a supplier over payment speed alone.

An Amex survey found 26% of B2B decision-makers ended a buyer or supplier relationship specifically because of late or slow payments.

In a B2B world where switching suppliers or buyers involves friction, renegotiated contracts, rebuilt trust, and operational disruption, that’s a remarkably high bar to clear. And 26% of respondents say payment speed alone cleared it.

Why This Number Is Larger Than It Looks

The B2B cross-border payments market reached $31.6 trillion in 2024 and is projected to reach $50 trillion by 2032. Apply a 26% “would end the relationship over payment friction” rate against a market growing at that scale, and the implied churn risk sitting inside slow payment infrastructure becomes genuinely enormous, not a minor operational inefficiency, but a structural threat to commercial relationships at a scale that should be sitting on every CFO’s risk register, not buried in a payments vendor’s marketing deck.

The same report frames the structural causes plainly: legacy infrastructure, data silos, and lagging technology adoption. Poorly formatted payment data and disparate legacy systems make it genuinely difficult to automatically match payments to invoices, which pushes companies toward manual, error-prone reconciliation processes, with no clear visibility for either side into where exactly the delay is happening.

The Specific Way This Plays Out in African Trade Corridors

This dynamic isn’t evenly distributed. It concentrates the hardest in exactly the corridors where banking infrastructure is least standardised, which, for global enterprises trading with African suppliers, means it’s already happening, quietly, inside relationships that look stable from the outside.

It looks like a relationship that slowly gets more expensive and less flexible for both sides, until eventually, as the Amex data shows, happens to roughly a quarter of B2B relationships, someone decides the friction costs more than switching does.

A buyer that can guarantee a supplier predictable, fast settlement, with transparent FX conversion rather than a hidden spread, is removing the single most commonly cited reason B2B relationships actually end.

For African suppliers specifically, who’ve historically absorbed the most settlement uncertainty in global trade relationships, a buyer who solves this becomes structurally easier to keep working with than one who doesn’t, independent of price or product considerations entirely.

For enterprises building or evaluating cross-border payment infrastructure in African markets specifically, this reframes the urgency. The question isn’t only “how much are we losing in fees and FX spread on current volume?” It’s “how many of our current supplier or buyer relationships are sitting closer to that 26% threshold than we realise, and what does it cost us if even a handful of them cross it?”
