How Often Should You Sync Billing Data to Postgres?
Daily, twice daily, weekly or monthly. How to pick a sync schedule for Stripe, QuickBooks, Xero or Paddle data, and why real-time is usually the wrong goal.
You have your billing data landing in Postgres. The connection works, the table is there, the first sync completed. Now there is a dropdown asking how often you want to repeat it, and no obvious way to answer.
The instinct is to pick the fastest option available, on the reasoning that fresher is better and the sync is automated anyway. That instinct is worth resisting. For billing data specifically, the right cadence is usually slower than people expect, and picking a faster one costs you in places that are not obvious on day one.
This post covers how to choose, how to match the sync mode to the schedule you picked, and the one case where scheduling is genuinely the wrong tool.
Start With the Decision, Not the Data
The useful question is not "how fresh could this be". It is "what decision am I making with it, and how often do I make that decision".
Billing data is consumed in a small number of recognisable ways, and almost all of them are periodic:
- Board reporting and investor updates. Monthly, occasionally quarterly. The numbers are cut at a month boundary and nothing that happens on a Tuesday afternoon changes them.
- MRR, churn and cohort dashboards. Reviewed weekly by most teams, daily by some. The underlying figures move slowly enough that hourly refreshes show noise, not signal.
- Month-end reconciliation. Intense for a few days, irrelevant for the rest of the month. Daily is comfortably enough, because the work happens against a closed period.
- Customer support lookups. Feels like it needs to be live, usually is not. Support agents overwhelmingly need "what plan is this person on and did their last invoice clear", which a daily copy answers correctly for the vast majority of tickets.
- Dunning and failed payment follow-up. The most time-sensitive of the common cases, and the one worth syncing twice a day for if you act on it manually.
If your use case is on that list, daily is the default answer and you should need a reason to move away from it. Weekly is right more often than people admit, particularly for accounting data from QuickBooks or Xero where the source system is itself updated in batches by a human.
What Actually Changes, and How Fast
The other half of the answer is how much your data really moves, which is usually less than it feels.
Customer records are close to static. A row changes when someone updates a card, an email or a billing address. For most SaaS businesses that is a low single-digit percentage of the table per month.
Subscriptions move more than they look like they do, because every status transition is a write: trialing to active, active to past_due, past_due to canceled, plus plan changes, quantity changes and renewals. Still, an individual subscription generates a handful of changes a year, not a day.
Invoices and charges are the genuinely busy tables, and they are lifecycle-heavy. An invoice moves through draft, open and paid, with a possible detour through a failed payment and a retry. But they are also the most predictable: they are created on billing anniversaries and settle within days.
Accounting data behaves differently again. QuickBooks and Xero records change when a person enters them, which means they arrive in bursts around invoicing runs and month end, and are quiet in between. Syncing a Xero ledger every hour mostly re-reads a ledger nobody has touched since yesterday.
The pattern across all four providers is the same: billing data changes in bursts tied to billing cycles and human work rhythms, not continuously. A schedule that matches those rhythms captures nearly everything a faster schedule would, at a fraction of the cost.
The Costs of Syncing Too Often
Faster schedules are not free, and the bill arrives in four places.
Your provider's rate limits. Stripe's published limits are 100 requests per second in live mode and 25 per second for an individual endpoint, which sounds like plenty. The constraint that actually bites is quieter: Stripe allocates read requests relative to your transaction count, at "an average of 500 per transaction" over a rolling 30 days, with a floor of 10,000 read requests per month. A business processing 100 transactions a month has a 50,000 read allocation, and a paginated full sync of several tables can consume a meaningful slice of that in a single run. Multiply by 24 runs a day and the arithmetic stops working. Xero is stricter still, with a per-tenant daily cap that starts at 1,000 calls a day on its entry tier. QuickBooks and Paddle both enforce their own per-minute limits.
Sync duration and overlap. Every run has fixed overhead: authenticating, paginating, comparing rows, writing. Schedule runs closer together than a run takes to finish and you get overlapping jobs competing for the same table, which is a good way to turn a working pipeline into an intermittent one.
Your own quota. Every managed sync tool meters something. Runs that produce no changes still consume your daily sync allowance, so an aggressive schedule spends your plan on re-reading unchanged rows.
Database write amplification. Frequent full syncs rewrite rows that did not change, which inflates your Postgres write volume and, on serverless hosts that bill on compute time, your database bill too.
None of these are catastrophic individually. Together they mean an hourly schedule on data that changes daily is pure waste.
Matching the Sync Mode to the Schedule
This is the part that most often goes wrong, and it matters more than the frequency itself.
A scheduled sync has two settings, not one: how often it runs, and how much data each run fetches. In Codeless Sync, a full sync is the default and re-reads everything in the table. The alternatives are fixed lookback windows: the last day, the last 7 days, or the last 30 days. These are windows, not a bookmark. A "last 7 days" run always asks for the last 7 days of changes, regardless of when the previous run happened or whether it succeeded.
That single detail drives the rule:
Your lookback window must be wider than the gap between runs. If they are equal, one failed or delayed run leaves a permanent hole in your data.
A daily schedule paired with a last-day window has zero margin. The run that fails at 2am on a Sunday silently loses Saturday's changes, and nothing later goes back for them. Pair a daily schedule with a last-7-days window instead and you get six days of self-healing overlap for almost no extra cost, because re-fetching a mostly-unchanged week is cheap.
Sensible pairings:
| Schedule | Lookback window | Why |
|---|---|---|
| Twice daily | Last 7 days | Wide safety margin, still a small fetch |
| Daily | Last 7 days | Six days of overlap absorbs failed or skipped runs |
| Weekly | Last 30 days | Covers a missed week and late-arriving edits |
| Monthly | Full sync | Volume is low enough that correctness beats efficiency |
| Any, small table | Full sync | Under a few thousand rows, just re-read it and stop thinking |
Full sync deserves more credit than it usually gets. It is the only mode that reliably reflects deletions and corrections made to historical records, which accounting systems produce constantly when someone amends last quarter's invoice. If your tables are small, full sync on a daily schedule is the most robust configuration available and the reason it is the default.
When Scheduling Is the Wrong Tool
There is a case where no schedule is correct, and it is worth naming plainly so you do not try to solve it with frequency.
If you need to react to an individual billing event within seconds, provisioning access the moment a payment clears, or emailing a customer the instant a card fails, that is not a reporting problem and a sync will not solve it at any cadence. Even a one-minute schedule gives you an average latency of thirty seconds and a worst case of sixty, with no ordering guarantees. Use the provider's webhooks for that specific workflow: they exist precisely for event-driven reactions, and they push in real time.
The mistake is assuming that because you need webhooks for one workflow, you need them for everything. Webhooks are excellent at "tell me when this one thing happens" and poor at "give me a complete, queryable table I can run SQL against", because they deliver events rather than state, they can be missed, and they never cover history. A scheduled sync is the opposite on all three counts.
Most teams end up wanting both, and that is a reasonable architecture: webhooks for the two or three events that trigger immediate action, a scheduled sync for the tables you query. We covered the trade-off in detail for Stripe and for Paddle.
Setting It Up
In Codeless Sync, scheduling lives on the configuration you already created. You pick a frequency, pick a sync mode, and the schedule runs without further involvement. Daily, weekly and monthly are available on every paid plan, and twice daily is available on Business. Free accounts sync manually.
Two practical notes. First, schedules are evaluated against a fixed time, so choose an hour that suits your reporting rather than leaving everything at midnight UTC, especially if your finance team works to a local month end. Second, a schedule only runs when the project, the configuration and the schedule itself are all active, so if runs stop appearing, check all three before assuming a failure.
The schedules documentation covers the mechanics, and how to use cron expressions for scheduled data syncs explains the syntax behind the presets. If you have not connected a database yet, the quick start takes about five minutes.
A Reasonable Default
If you want to stop reading and just pick something:
Daily, with a last-7-days window, at an hour that suits your reporting. Move to twice daily only if you act on dunning manually. Move to weekly if your data is accounting-led and entered by hand. Switch to full sync if your tables are small or your source system amends historical records.
You can change it later. That is rather the point of not agonising over it now.
Frequently Asked Questions
How often should I sync Stripe data to Postgres?
Daily suits almost every reporting, dashboard and reconciliation use case. Twice daily is worth it if you manually work failed payments. Faster than that rarely changes a decision, and it consumes your Stripe read allocation, which is capped relative to your transaction volume rather than being unlimited.
Is real-time syncing better?
Not for billing data. Real-time is better for reacting to individual events, which is a webhook's job. For a queryable table you run SQL against, a scheduled sync gives you completeness and history, which matter more than latency for reporting.
What happens if a scheduled sync fails?
The next scheduled run goes ahead as normal. Because lookback windows are fixed rather than resuming from a bookmark, a failed run is only self-correcting if your window is wider than your schedule interval. A daily schedule with a last-7-days window recovers automatically. A daily schedule with a last-day window does not.
Should I use full sync or an incremental window?
Full sync if your tables are small, or if your source system amends historical records, since it is the mode that reflects deletions and corrections. An incremental window once the table is large enough that re-reading it every run is wasteful. Full sync is the default for that reason.
Does syncing more often cost more?
The subscription price does not change, but each run counts against your daily sync allowance, and every provider enforces API rate limits. Frequent full syncs also increase Postgres write volume, which can matter on hosts that bill by compute time.
Can I sync different tables on different schedules?
Yes. Scheduling is set per configuration, so you can run invoices daily and customers weekly by creating separate configurations. This is usually a better use of your sync allowance than putting everything on the fastest schedule.
Wrapping Up
The honest answer to "how often should I sync" is "less often than you first assumed, with a wider lookback window than you first assumed".
Billing data moves in bursts tied to billing cycles, and the decisions you make with it are periodic. Matching your schedule to those rhythms, and leaving enough overlap that a failed run heals itself, gets you a more reliable pipeline than chasing freshness ever will.
See the pricing page for which schedules come with which plan, or start on the free tier and sync manually until you know what cadence you actually need.
