A common question early in setup: "Do I need six bank accounts to match my six reserves?" The answer is almost always no. ReservWise reserves are virtual — they slice your real money into named buckets without requiring those buckets to live in different bank accounts. One checking account can hold all six reserves and still let you run the system cleanly.
That said, real bank accounts do have one advantage that virtual reserves don't: they earn interest, and they're a physical barrier against accidentally spending money you've earmarked. So there's a real trade-off worth thinking through.
The default setup we recommend
For most operators, two bank accounts is enough:
- Operating account. A business checking account where income lands and from which day-to-day spend goes. Holds Survival, Business Ops, and (working portion of) Lifestyle.
- Reserve account. A separate high-yield savings account that holds Tax, Growth, and Wealth Building. Money flows here on a schedule (manual or automated) once it's been allocated.
ReservWise reserves layer on top of these accounts. The dashboard tells you that Tax should hold $4,200; the high-yield savings account is where those $4,200 actually live. The dashboard tells you that Growth should hold $1,800; same place. You don't need a separate account per reserve.
Why two and not one
- Interest. Tax, Growth, and Wealth tend to hold real balances over months — putting them in a high-yield account earns 4–5% APY in current US conditions, money you'd otherwise leave on the table.
- Friction against accident. Tax money in your operating account is a tax payment that "almost happened." Tax money in a separate account requires a deliberate transfer to spend, which means you're less likely to spend it by mistake.
- Cleaner reconciliation. Your operating account ties to Plaid for automatic categorization. Your reserve account doesn't need to — it's a safe — and that simplicity reduces noise on the dashboard.
Why not six accounts
- Bank accounts have minimums and fees. Six accounts at most banks costs money you don't need to spend.
- Plaid limits and stability. Each connected account is another link to maintain. Fewer is more reliable.
- Cognitive overhead. ReservWise already names and tracks the buckets. Mirroring that structure in real accounts duplicates the work.
- Nothing materially improves. The discipline benefit comes from separating spending money from reserve money. Once you've made that one cut, additional cuts add complexity without adding control.
When more accounts make sense
There are real cases where you'll want extra real-world separation:
- Multi-entity businesses. If you run two LLCs, they need separate accounts for legal and tax reasons. ReservWise supports separate workspaces per entity.
- Joint-and-personal split. Some operators keep Wealth Building in a personal investment account separate from any business banking. Fine — point ReservWise at the right account in Settings → Accounts.
- Trust or designated accounts. Required by law in some industries (lawyers' IOLTA, certain real estate accounts). Use the legal account; ReservWise tracks it like any other.
- Significant interest-rate spread. If you find a CD or T-bill ladder paying meaningfully more than your high-yield savings, parking Wealth or long-term Tax there is reasonable. Just remember the liquidity trade-off.
How money actually moves between accounts
ReservWise doesn't move your real money — it tracks where it should be. You move it, on whatever cadence you prefer:
- Weekly sweep. Each week, move the dashboard-stated total of Tax + Growth + Wealth from operating into reserve account.
- Per-deposit sweep. Each time a large invoice lands, sweep the allocated reserve portions immediately.
- Monthly true-up. Reconcile once a month: dashboard says reserves should hold $X; reserve account holds $X. Adjust.
Most banks support automated transfers between linked accounts. Setting up a weekly auto-transfer of a fixed minimum (say, $500) and topping up manually after big deposits is a low-effort middle path.
Keeping virtual and real in sync
The Reconciliation view (Reports → Reconciliation) shows two columns side by side: ReservWise's accounting of where each dollar is, and what your linked bank accounts actually hold. Drift between them is normal — a few hundred dollars during a billing cycle, nothing alarming. Drift in the thousands means a sweep is overdue or a transaction wasn't categorized.
What to do next
- If you only have one bank account today, open a high-yield savings account and treat it as your reserve account. That single change is worth more than any reserve restructuring.
- Set up Plaid against your operating account so income detection is automatic. See Connecting Plaid.
- Once a week, sweep Tax + Growth + Wealth balances from operating to reserve. After a month it'll be reflexive.
Reserves are how you think about your money. Bank accounts are where it sits. Two accounts and one good dashboard is the answer for almost everyone.
