missing hyphen in 'per user basis'

Quick answer

Hyphenate per-user when the phrase directly modifies a noun: use a per-user basis. If the phrase follows the noun or acts adverbially (The fee is per user), don't hyphenate. When unclear, rewrite to for each user, per account, or We bill each user monthly.

Correct (modifier before noun): a per-user basis
Correct (adverbial/predicate after verb): The fee is per user
Rewrite option to avoid hyphens: for each user / per account / per-seat pricing

Core rule: compound modifiers before a noun get hyphens

When two or more words form a single idea that describes a noun, hyphenate them to show they work together. per-user is a compound modifier describing what kind of basis-one that applies to each user.

Quick diagnostic: if the phrase sits directly before the noun it describes, hyphenate; if it follows the noun or is used adverbially, don't.

Before the noun (hyphenate): a per-user basis, per-user pricing, per-user limits
After the verb (no hyphen): The fee is per user; We bill per user
When in doubt, rewrite: for each user, per account, per-seat pricing

Wrong → Right: Wrong: We offer pricing on a per user basis. →
Right: We offer pricing on a per-user basis.
Wrong → Right: Wrong: Apply quotas per user basis. →
Right: Apply quotas on a per-user basis.

Hyphenation & style guides (what editors expect)

Most major style guides recommend hyphenating compound modifiers that appear before a noun when hyphenation prevents misreading. Technical, legal, and marketing copy should favor the hyphen for precision.

Short UI labels and casual chat are less strict; still, if the phrase modifies a noun in customer-facing copy, prefer the hyphen.

Chicago/AP: hyphenate compound modifiers to avoid ambiguity
Technical/legal/marketing: prefer hyphenation for clarity
Internal chat/UI labels: prioritize readability and consistency

Spacing and punctuation: the exact character to use

Use a single hyphen-minus (-) with no spaces: per-user. Don't use spaced hyphens (per - user), en dashes, or underscores.

Don't chain hyphens unnecessarily-per-user-basis looks wrong. Put a single hyphen between modifier words and a space before the noun.

Correct: per-user basis
Wrong: per - user basis (spaces around the hyphen)
Wrong: per_user or per-user (underscore or en dash)

Grammar nuance: when you should not hyphenate

If per user follows the noun or acts as an adverbial phrase, you normally don't hyphenate: The license is per user. Hyphenating there looks odd and can read like a typo.

If stacked modifiers would produce chains of hyphens, rewrite: per user per month → We bill each user monthly.

Predicate/adverbial use: no hyphen - The rate is per user.
Avoid chaining hyphens: rewrite per-user-per-month into a clearer sentence.
When clarity wins, rewrite: for each user / per seat / per account.

Wrong → Right: Wrong: The rate is per-user. →
Right: The rate is per user.
Rewrite example: Pricing is per user per month → Better: We bill each user monthly.

Real usage & tone: pick the hyphen to match your audience

For product docs, legal terms, and marketing aimed at buyers, hyphenate (per-user) for precision and polish. In chat or casual updates where the phrase follows the verb, you can skip it.

When unsure, prefer a short rewrite that removes ambiguity and often reads better: for each user, per seat, or per account.

Technical/legal: use per-user when it modifies a noun
Marketing: hyphen improves readability and perceived professionalism
Casual/internal: predicate forms (The fee is per user) or rewrites work fine

Work (formal): Per-user access policies are enforced across the platform. - hyphenated and professional.
Casual (chat): We charge per user for that add-on. - acceptable without hyphen because it follows the verb.
Marketing: Per-User Pricing That Scales With Your Team. - hyphenated to keep the modifier tight and eye-catching.

Memory trick and reusable patterns

Ask: "What kind of X?" If the multiword phrase answers that and comes before X, hyphenate. Example: "What kind of basis?" → per-user basis → hyphenate.

Mnemonic: If it answers "What kind of X?" and sits before X, hyphenate.
Patterns: per-student basis, per-project budget, per-account setting, per-seat pricing - hyphenate before nouns.
If the phrase follows the noun or you can rewrite to for each X, hyphenation is usually unnecessary.

Similar mistakes to watch for

The same rule applies to many compound modifiers: user friendly → user-friendly, low cost → low-cost, long term → long-term. Watch stacked compounds and long modifiers before nouns.

Wrong: per person basis →
Right: per-person basis
Wrong: user friendly interface →
Right: user-friendly interface
Avoid stacked hyphens: per-user-per-month → Rewrite: per user per month or We bill each user monthly
Other traps: hyphenate long modifiers before nouns (low-cost, full-time, long-term)

Wrong → Right: Wrong: We bill on a per person basis. →
Right: We bill on a per-person basis.
Wrong → Right: Wrong: The interface is user friendly. →
Right: The interface is user-friendly.
Wrong → Right: Wrong: Pricing is per user per month (ambiguous). →
