How do I buy credits or add-ons?

One-off SMS, email and marketing credit packs that never expire, plus the monthly Extra Storage add-on.

Open Account → Add-Ons. There are two different things here: one-off credit packs you buy once and keep, and monthly add-ons that bill every cycle. Only the account owner can buy either — purchases charge the account's card.

One-off credit packs

Up to three sections: SMS credit packages, Transactional email credit packages (Free plan with no paid product only — every paid plan and paid product includes unlimited transactional email, so that section becomes a simple note there) and Marketing email credit packages. Each shows a usage meter and a choice of pack sizes with the price on each card — paid plans get a loyalty discount (5% on Plus and Pro, 10% on Complete), shown as a strikethrough price; the discount comes from your venue plan, so a products-only account pays the list price. Purchased credits never expire and are only used after your monthly allowance runs out, so they carry over between cycles. They also survive a plan change: if you later downgrade to a plan without an SMS allowance, your text messages keep sending from the purchased credit balance until it runs out.

• Expand the section and click Purchase on a pack.
• The confirm pop-up shows the pack and price, and which card will be charged ("Charged to … ending …"). You can open Have a code? to apply a credit-pack discount code, or choose Use a different card.
• Click Confirm & pay — you'll be asked to confirm your password. The credits appear on your balance moments later, and the purchase lands in your invoice history as a Credit top-up.

SMS packs need SMS notifications — included on Plus and above, and with any paid ResoFlow product (Gift Cards, Loyalty, Tickets or Order & Pay); without either, the section shows Available on Plus plan and above alongside the product route. Marketing packs need marketing tools — Pro and above, or any paid product; locked, the section shows Available on Pro plan and above with the product route (e.g. "Included with Gift Cards — £25/month"). Standalone products include no monthly SMS or marketing email allowance — on a product-only venue, sends come entirely from purchased packs.

Monthly add-ons

• Extra Storage — £2/month per GB of extra image storage (all your images share one pool — see How does the image library work?); add or remove GBs any time.

Click Add storage (or Change quantity if you already have it), review the prorated charge preview, then Confirm & charge — again confirming your password. Adding is immediate and prorated; removing (Remove) or reducing the quantity takes effect at the end of the billing cycle, and until then a Keep subscription button lets you cancel the pending removal. It needs an active paid subscription (the button reads Upgrade plan first otherwise).

Where balances show: your credit balances and active add-ons appear on Account → Plan & Usage (top-up balances row and the Active add-ons card).

One more thing worth knowing: if ResoFlow has given your venue something free — a comped add-on or product — it never just switches off silently. You get a "Your free X ends on {date}" email a week before it ends and a "Your free X has ended" email on the day, with matching bell notifications.
