Macha Credit Top-Up Packs: More Credits Without Changing Your Plan

This post is the practical guide to how top-ups work in Macha — what the packs cost, how the balance behaves, who can buy them, and the honest cases where topping up is not the right move (sometimes you really should just change plans). If you're new to how Macha meters work at all, the short version: credits are spent per AI action, billed by the model you run (0.5–9 credits each, with the default GPT-5.4 Mini at 1). Top-ups are simply more of that same currency.

What a top-up pack actually is

A top-up pack is a one-time purchase of credits that lands in your account on top of your monthly plan allowance. You don't change your plan, you don't sign a new contract, and you don't get billed again next month for the same block. You buy it from the billing page, a Chargebee one-time checkout opens in an in-page popup, you pay, and the credits appear.

There are three packs, sized for three different kinds of "we need more this month":

The bigger the pack, the lower the per-credit rate — the Large pack works out cheaper per credit than the Small one, the usual volume curve. (All prices are pulled live; see the pricing page for the current figures.)

The one rule that makes top-ups effortless: monthly first, top-up second

The single most important thing to understand about top-up credits is the spend order. Macha always spends your monthly plan allowance first, and only dips into your top-up balance once the monthly allowance is exhausted. You never have to choose which bucket to draw from, and you never accidentally burn through a top-up you bought for a rainy day while your included credits sit unused.

That ordering has a second, quieter benefit: top-up credits never expire. Monthly credits reset on each billing cycle — use them or lose them. Top-ups don't. A pack you buy in June is still there in September if your monthly allowance kept covering you in the meantime. So a top-up is never wasted money; at worst it's money you spent a little early.

This is the same model the broader AI-tooling world has converged on. JetBrains documents it almost word for word: "AI Assistant starts using your Top-up AI Credits only after your monthly quota is fully used… Once the new monthly quota becomes available, AI Assistant switches back to using it." OpenAI runs the same shape in ChatGPT — Plus and Pro users who hit their limit can buy extra credits "to continue working without needing to upgrade." Tools like Descript and Adobe have landed on variations of it too. Everyone arrives at the same rule because it's the one that doesn't punish customers for buying ahead. (One difference worth flagging: OpenAI's and JetBrains' top-up credits expire after about a year; Macha's don't.)

The billing page makes the two balances legible instead of mashing them into one number:

When you do have a top-up balance, a green +N top-up chip appears right next to your monthly count, with a hover that explains the persist-and-spend-after rule — so the extra credits are always visible, never a hidden line item.

Who can buy top-ups (and who doesn't need to)

Top-up packs appear on the billing page for active Starter and Professional subscriptions. That covers the teams the feature is built for — paying customers on a fixed monthly allowance who occasionally run hot.

Two groups see something different on purpose:

• Trial users don't get top-ups. If you're on a 7-day free trial, no credit card required and you're already pushing the limits, the right move is to start a paid plan, not to bolt credits onto a trial — so the flow nudges you to upgrade first.
• Enterprise plans don't need them. Enterprise runs with bypassed credit checks (effectively unlimited credits), so there's no allowance to top up.

There's also some unglamorous-but-important plumbing worth a sentence: top-up purchases are recorded against the Chargebee invoice ID as a unique key, so if a payment webhook gets delivered twice — which happens — your account can't be double-credited or double-charged off the back of it. It's the kind of detail you only notice when it's missing.

A worked example: the launch-week spike

Say you're on Professional with its monthly allowance, and a Black Friday push triples your inbound for ten days. You're going to blow through the month's credits with two weeks still on the clock. Your options:

1. Upgrade to a higher plan. Now you pay the higher monthly fee every month, forever, to cover one spike. For a genuinely one-off event, that's overkill.
2. Buy a Large top-up. One purchase of 10,000 credits at $0.080 per credit, the agents keep resolving tickets through the rush, and next month you're back to your normal allowance with the unused top-up credits still banked for the next spike.

For episodic demand — launches, sales, seasonal peaks, a one-time Studies batch run over your back-catalogue of tickets — option 2 is almost always the cheaper, lower-commitment call. The deep link makes this concrete: from the Studies Review screen, a "Need more? Buy a top-up pack" link sits right next to the credits-remaining pill, so when an estimate is bigger than your remaining balance you can top up in two clicks without losing your place.

The honest part: when you should change plans instead

Top-ups are a convenience, not a loophole, and there's a real trade-off in the per-credit math. Because the packs are one-time purchases, they're priced above the per-credit rate you get baked into a monthly plan:

The pattern to read off that table: a top-up credit costs more than a credit included in a higher monthly plan. So the decision rule is simple and worth stating plainly:

• If your overage is occasional — a spike here, a one-off batch there — top up. You pay a small premium per credit, but only on the credits you actually needed, and you never raise your recurring bill.
• If you're consistently running out every single month, the slightly higher per-credit cost of top-ups starts to add up, and a plan upgrade is the cheaper, cleaner answer. Higher tiers come with more included credits at a lower baseline rate, plus more integrations, agents, and knowledge sources. Buying three top-ups a month, every month, is a signal you've outgrown your tier — and the billing page is telling you to move up, not to keep patching.

This is the opposite of how some of the market prices overage. Intercom's Fin, for instance, charges $0.99 per resolution beyond the bundle included in your plan, and Intercom does not publish a volume discount on that rate — it's a per-outcome meter that climbs with every success. Macha's top-ups are flat blocks of the same per-action credits you already spend, priced down as the packs get bigger (the Large pack's per-credit rate is below the Small pack's), and never billed twice for the same invoice. We'd rather you buy exactly what you need and stop, than be metered on every win.

FAQ

Do top-up credits expire? No. Unlike monthly plan credits, which reset each billing cycle, top-up credits roll over indefinitely until you spend them.

Which gets spent first, my monthly credits or my top-up? Your monthly plan allowance always spends first. Macha only draws on your top-up balance after the monthly credits for the cycle are used up, so a top-up is never burned prematurely.

Do I need to change my plan to buy a top-up? No — that's the whole point. Top-ups sit on top of your existing Starter or Professional plan. Nothing about your subscription, billing date, or monthly fee changes.

Can trial or Enterprise users buy top-ups? Trial users can't — the flow asks you to start a paid plan first. Enterprise plans don't need them, since they run with unlimited credits.

How do I actually buy one? From the billing page, pick a pack and click Buy. A Chargebee checkout opens in an in-page popup; once payment completes, the credits appear on your Usage card as a separate top-up balance.

Should I top up or upgrade? Top up for occasional, episodic spikes — you only pay for the extra credits you needed. Upgrade if you're running out every month, because included plan credits carry a lower per-credit rate than one-time packs. See the pricing page to compare.

The bottom line

Credit top-up packs close the gap between "my plan fits us 11 months a year" and "but this month is different." Buy a block once, keep your agents working through the spike, and let any leftover credits wait — interest-free, expiry-free — for the next one. For everything else, the plans are right there.
