Slack for Invoicing?

Slack for Invoicing?

Who knew Slack would become my preferred invoicing tool?

Not talking about any kind of integration or new AI feature either.

Selling methods keep evolving - channels, tools, motions. What looked like best practice five years ago barely resembles what works today.

But one thing hasn’t changed: 𝐭𝐫𝐮𝐬𝐭 is still the foundation of every lasting client relationship.

In my early selling days, I used to dread invoice conversations - sending overly formal emails, agonizing over exact wording, over-explaining every line item.

Then I realized the problem wasn’t the invoice. It was the relationship.

Because of the trust I’ve built with my clients, my favourite recurring feedback is that it feels like I'm part of their internal team.

They trust my knowledge, they trust the tool, and they trust me enough to pull me into their Slack channels.

And when that trust is there? A “renewal invoice coming up in 45 days 👀” Slack message doesn’t feel unprofessional - it’s just a helpful nudge between colleagues.

So I’ve scrapped the formality where it doesn’t belong. Slack reminders have sped up my invoicing process immensely - but more importantly, they reflect the relationship underneath.

Being in their Slack shifts the whole dynamic. Instead of feeling like a vendor sweating over a renewal, it feels like a routine ops decision between people who already trust each other.

But none of that happened overnight.

Establishing trust early enables so much downstream effect. It should be paramount to anyone trying to build long-lasting client relationships.

For me, that usually means more laborious, consultative work upfront - but it always makes everything that follows much smoother.

(Shameless plug: it doesn’t hurt when your product is also about trust... ARRow exists to give teams full confidence in their numbers 😉).
